Air filter is an air filter, which is usually used in clean workshop, clean workshop, clean operation room, laboratory and clean room, or for electronic machinery communication equipment. It is widely used in oil, chemical, metallurgical, electricity, machinery, light industry, textile, automobile manufacturing, electronics, food, medicine, biochemistry, national defense, scientific research and other industries and departments that need to compress air purification.

Methods of cleaning the air filter:

1. when the surface of the filter is not dirty, take the filter to the outside, clean it with clean air, blow it to the side, and blow it to the eye.

2. when the filter surface is dirty, it needs to be washed. In the general area of the water making room (air conditioning) in the tank of about 100 Jin of reference water, 1 jin of the bottle of detergent diluted, put the filter into the tank to be completely submerged in the water. Rinse a number of times, until no pollution. Finally rinse with clear water until the water is cleaned until the water is cleaned. Remove the dry water over the stainless steel grille, then spread it on the shelf, and turn it on both sides to speed up the drying speed.

3. clean the external surface and accessory pipes and meters of the air conditioner with a rag every day to make the equipment clean and bright.

4. the oil and glue on the equipment should be wiped out with a cloth cloth detergent and then cleaned with drinking water without leaving any trace.

5. after the replacement of the initial and medium effect filters, the internal panels, fans, heaters, coolers and diffuser plates of the air conditioning unit should be cleaned thoroughly. Dust, dirt and oil stains should be cleaned, and no dead angle should be retained. Then the initial and medium effect filters should be reinstalled.

6. clean the system once every half a month. First wipe the interior with a wet cloth, then use a dry cloth to clean it.

7. when replacing the high efficiency filter, the four frame of the installation filter and the surrounding wet clean cloth should be cleaned, and it should be repeated three times. The high efficiency filter should be installed immediately after the wipe. The high efficiency filter should be unpacked at the scene and checked immediately after being qualified, so as to prevent dust falling into the high efficiency filter.

8. the number of suspended particles in the clean room is obviously exceeded, and the final air volume of the high efficiency filter falls below 70% of the initial air volume.

9. after the high efficiency filter is replaced, the dust particle counter performs leak detection on the high efficiency filter and the installation joint. While scanning and inspecting, fastening bolts or plugging with epoxy resin silica gel.

10. the inspection and replacement of high efficiency filters should be recorded in time.

11. after the replacement of the high efficiency filter, leak test should be carried out and verified.

Attention to air filter:

After 1. filter cloth is cleaned, if the initial resistance value of the filter is lower than the initial resistance value of the first installation and use of the filter, it should not be used and should be replaced in time. After 2 cleaning, the filter should be replaced even if the pressure difference is greater than the initial value.

2. when the high efficiency filter is applied, the suitcase should be inverted so that the filter can land smoothly.

3. after the filter is cleaned, check whether there is any breakage, if necessary, replace it in time, do not rub it when washing, do not machine wash or dry.

4. during the cleaning process, no confusion should be given between the primary and intermediate filters, and the numbers should be numbered to distinguish them.

5. each air purification system should have a set of filters to be replaced in time for cleaning.
